CHENILLE;`r`

SPECIFICATION forming part of 'Letters Patent` No.` 224,438, dated February 10, 1,880.

' Application filed November '7, 1879 1. Fig. 3 is a horizontal section of the mechanism which I use in carrying out my invention, the plane of section being indicated by the line y y, Fig. 4. Fig. 4 isa sectional side view of the same.

Similar letters indicate corresponding parts. This invention relates to uncut chenille hav-l ing sections of different thicknesses.

A, of two threads of cotton or other equivalent material, a covering, B, of silk or other equivalent material, and two.bindingthreads, b b', which serve to fasten and retain the covering 2 5 B upon the straight core A. The covering B is laid on in the form Vof a spiral(see Fig. 1) the diameter of r which increases and diminishes, so that my chenille, when finished, presents the appearance shown in Fig. 1, showing sections of small diameter alternating with other sections of larger diameter. This object is obtained by winding the covering-thread, before the same is secured upon the core A, around two fingers, the distance between which can be increased* or diminished at pleasure.

In order to enable othersl skilled in the art to fully understand and carry out my invention, I have shown in the drawings the principal part-s of the mechanism which I use in the manufacture of my chenille. y

In these drawings, the letter Odesignates a spool which carries the covering-thread or silk, and which revolves loosely on a tubular stationary shaft, D. On this tube is fastened a platform, E, provided with lugs d, each of which supports a nger, e. (See Fig. 3.) The innerends of these Afingers are made in the form of springs, which have a tendency to force the tips of said ngers toward each other, and

My chenille is composed of a straight core,

between said lingers is situated a spreader, f, 5o which is secured to a rod, g, extending through the tubular shaft D.

The outer end of the V,rod g, Fig. 4., is connected to a lever, h, which is subjected to the action of a cam, so that a reciprocating motion 5 5 is imparted tov the spreader f, causing the same to spread the fingers e open or to allow them toclose. The spiral of the coveringthread is. formed near the tipsof the fingers e, and as these fingers open or close the diame- 6o ter of this spiral increases or diminishes.

Through they tubular shaft D extend two threads, c a', which are intended to form the core -A, and the binding-threads b b extend over rollers it. one of which is situated'above 65 and the other below the tips of the fingers e.

At the beginning of the operation the ends of the threads a afb b are connected to an ordinary twister, and when the mechanism is set in motion all these threads are twisted to- 7o of an open spiral,`the coils of this spiral are Vdrawn in'between the twists of the bindinglthreads b b` as the same are twisted around the straight core A, and an article is produced such as shown in Figs. 1 and 2. -v

In the example shownin Fig. 1 the diameter of the different sections of my chenille increases and decreases gradually; but' it will 8o be readily understood from'the above description that by allowing the fingers e to remain stationary for a certain time the diameter of the chenille manufactured during that time will -vremain uniform, and if the fingers are 8 5 then spread open the'diameter of the succeed- ,ing section of the chenille will be increased correspondingly. I do not, therefore, desire to confine myself to the precise form of the che? nille shown in the drawings. y 9o I am aware that a cnt chenille has been made in which the chenille-threads'are held between two cords twisted together, and that these chenille-threads have varied in length, in sections,"so as to give the trimming a vary- 9 5' ing diameter; but it will be discovered that the means employed for the manufacture of such a trimming are entirely inadequate to An uncut chenille consisting of a straight core having a covering or wrapping coiled around it in sections of different diameters,

and having binding-threads coiled around vsaid wrapping and binding it to the straight core, whereby a series of loops are arranged in a spiral course around the core and project radially therefroml in all directions, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand and seal this 3d day of November, 1879.
